Female cuckold

If one woman openly relaxs with another woman's husband. makes no effort to hide it and actually rubs the other woman's nose in it because she is so much better in the sack does that make the wife a cuckold or can it only be applied to men ?

From the reading and research I've done both males and females can be cuckolds its just not as commonly acknowledged and embraced by females as it appears to be by males (at least here)...but this is simply my opinion. I've never deliberately made it known to any of the wives whose husbands I may have fucked. Not my style.
I am a truly blessed Lady who is still learning and enjoying myself immensely at my hubby's expense. :) I love a cuckolded husband.
